Mixed-cation perovskite solar cells in space

Abstract: With the continuous improvement of efficiency and stability, perovskite solar cells are gradually approaching practical applications. PSCs may show the special application in space where oxygen and moisture (two major stressors for stability) barely exist. Publishing in Sci. ChinaPhys. Mech. Astron., a group of researchers at Peking University in China, led by Dr. Rui Zhu and Prof. Qihuang Gong in collaboration with Prof. Guoning Xu from Academy of Opto-Electronics, CAS, and Prof. Wei Huang from Northwestern Polytechnical University, have reported the stability study of PSCs in near space.

n-Alkanes Phase Change Materials and Their Microencapsulation for Thermal Energy Storage: A Critical Review

Abstract: n-Alkanes and their blends are characterized as phase change materials (PCMs) due to their superior thermodynamic performances, for storing thermal energy in various practical applications (solar or wind energy). Such materials present some limitations, including lower thermal conductivity, supercooling, phase segregation, and volume expansion, among others. To address these problems, microencapsulation of n-alkanes and their blends is being successfully developed. A considerable amount of work has been published in this regard. Hence, the aim of this review is focused on two aspects: summarize the pure n-alkanes and their blends PCMs; describe their microencapsulation. PCM-interesting characteristics (transition temperatures and enthalpies) of pure n-alkanes, multinary alkanes, and paraffins (over 140 types) were listed, while the phase equilibrium evaluations of multinary alkanes were elaborated on. The essential information, core and shell materials, crystallization and melting characteristics, encapsu...

Latest Advances in High-Voltage and High-Energy-Density Aqueous Rechargeable Batteries

Abstract: Aqueous rechargeable batteries (ARBs) have become a lively research theme due to their advantages of low cost, safety, environmental friendliness, and easy manufacturing. However, since its inception, the aqueous solution energy storage system has always faced some problems, which hinders its development, such as the narrow electrochemical stability window of water, poor percolation of electrode materials, and low energy density. In recent years, to overcome the shortcomings of the aqueous solution-based energy storage system, some very pioneering work has been done, which also provides a great inspiration for further research and development of future high-performance aqueous energy storage systems. In this paper, the latest advances in various ARBs with high voltage and high energy density are reviewed. These include aqueous rechargeable lithium, sodium, potassium, ammonium, zinc, magnesium, calcium, and aluminum batteries. Further challenges are pointed out. Aqueous can be better in terms of safety, friendliness, and energy density.
